IMPROVEMENT IN EARTH-BORING AUGERS.

Specification forming part of Letters Patent No. 117,542, dated August l, 1871.

To all whom it may concern:

Be it known that INVILLIAM WHEETEN J iLz, of Hamilton, in the county of Caldwell and State of Missouri, have invented anew and useful Improvementin Earth-BoringAuger 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention rela-tes to a new and useful improvement in augers for boring wells, whereby much valuable time is saved 5 and it consists in forming the auger of a longitudinal section of a hollow cylinder flattened on its back so as to admit air, and provided with a cutting-bit and circular lip, the whole constructed to operate as hereinafter more fully described.

In the accompanying; drawing, Figure 1 repreresents a front view, having' a swinging door or iiap hinged to it, which door is used in certain kinds of boring. Fig. `2 isa oross-section of l taken on the line :c a.

Similarletters of reference indicate corresponding parts.

A is the auger, which consists of a longitudinal section of a tube iiattened for a small space its entire length, as seen at B. C represents the bit, which projects down below the end ot' the semiciI-.cular auger so as to enter the earth. l)

isa horizontal lip which receives and supports the column of earth when the auger is withdrawn.

The bit works downward as the auger is revolved, and theearth which is thus undermined is left stationary with the auger, andwhen the pod or au ger is full it is raised, and swinging, as it does, from a derrick, it is turnedina horizontal position with the open side down, when the earth drops by 4its own gravity. Water is used during the process of boring with this auger, which greatly diminishes the friction. Air is constantly admitted to the auger by means of the flattened space B on the back, which prevents a vacuum being formed to retard or obstruct the withdrawal of the auger. With this anger the, earth is readily bored to the depth of a hundred feet or more. The auger is attached to the end of a wooden rod, to which the power is .directly applied.

There is a band around the semi-cylinder near the top, two inches under, more or less, as indicated by dotted lines inthe drawing', the object of which is to support the load in the auger (tenacious clay, for instance) and prevent its discharge from the auger before the proper time.

The ad vanta gesoi this au ger over the ordinary earth-angers in use are many, and must be obvious to all who are acquainted with the subject. 4 Having thus described my invention, I claim as new and desire to secure by Letters Patent- A semicircular auger, iiattened at B to admit air, combined with bit C having the horizontal lip D to support the core of earth, as and for the purpose specified.
